Feature: Git environment variables are respected and used instead of using the current working directory.


  Scenario Outline:
    Given the repository "<repository>" is cloned and checked out at the commit "<checkout_commit>".
    When the argument --from-commit-hash is provided as "<from_commit_hash>".
    And the argument --from-version is provided as "<from_version>".
    And the argument --current-version is provided as "<current_version>".
    Then the current version assertion passes.
    Given the GIT_DIR environment variable is set to the cloned repository.
    Then the current version assertion passes.


    Examples:
      | repository                                   | checkout_commit                          | from_commit_hash                         | from_version | current_version |

  Scenario Outline:
    Given the repository "<repository>" is cloned and checked out at the commit "<checkout_commit>".
    When the argument --from-commit-hash is provided as "<from_commit_hash>".
    And the argument --from-version is provided as "<from_version>".
    And the argument --current-version is provided as "<current_version>".
    Then the current version assertion fails.
    Given the GIT_DIR environment variable is set to the cloned repository.
    Then the current version assertion fails.

  Scenario Outline:
    Given the repository "<repository>" is cloned and checked out at the commit "<checkout_commit>".
    When the argument --from-reference is provided as "<from_reference>".
    And the argument --from-version is provided as "<from_version>".
    Then the returned version should be "<expected_version>".
    Given the GIT_DIR environment variable is set to the cloned repository.
    Then the returned version should be "<expected_version>".


    Examples:
      | repository                         | checkout_commit                          | from_reference | from_version | expected_version |

  Scenario Outline: You can also provide the long name and partial names not just the short name.
    Given the repository "<repository>" is cloned and checked out at the commit "<checkout_commit>".
    When the argument --from-reference is provided as "<from_reference>".
    And the argument --from-version is provided as "<from_version>".
    Then the returned version should be "<expected_version>".
    Given the GIT_DIR environment variable is set to the cloned repository.
    Then the returned version should be "<expected_version>".
